CARBONATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 609,867, dated August 80, 1898. Application iiled April 24, 1897. Serial Noi 633,734. (No model.)

To all whom, t may concern.-

Be it known that I, CHARLES L. BASTIAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new andruseful Improvements in Carbonating Apparatus, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this speciiication.

My invention relates to certain new and useful improvements in carbonating apparatus in which carbonic-acid gas under pressure is combined with water or other liquid to produce a carbonated beverage.

The object of my invention is to provide an apparatus of the character described which will operate and govern itself automatically to regulate the amount of liquid or gas supplied.

Another objectof the invention is to cause the liquid to absorb a greater amount of gas than has heretofore been possible with apparatus of this character; and a further object of the invention is to provide suitable means for automatically distributing' the liquid in such a manner throughout the mixing-chamber that the gas may penetrate it and be absorbed thereby in large quantities.

My invention also has certain other objects, which will be specifically pointed out and claimed hereinafter.

In the accompanying drawings, Figure lis a side elevation of my improved apparatus, showing the same adapted for use, a balanced tank being provided for automatically controlling the supply of liquid to the mixer. Fig. 2 is a detail sectional view of the valve. Fig. 3 is a sectional view of the upper end of the saturating-chamber, showing the distributing device and the wire-gauze within said chamber. Fig. 4. is a side elevation of the apparatus, shown partly in section to illustrate particularly the manner in which the liquidsupply may be automatically controlled electrically. Fig. 5 is a top plan view of the electrical devices connected with the valve-stem, showing the manner in which the same are adapted to operate.

Referring to the drawings, in which like letters of reference denote corresponding parts in all of the figures, the mixer comprises I a collecting-tank A, supported in a suitable manner on the legs a, and B is a saturatingchamber mounted on the tank and connecting therewith and provided with a pressuregage b. Gas is admitted to the lower part of the collecting-tank through the pipe C, which is connected at its other end in a suitable manner with one or more gas-cylinders D, a regulating-valve c and a pressure-gage d being located intermediate of the gas-cylinder and the collecting-tank. A pump E is supported in a frame c and is operated bya crank-shaft c, journaled in suitable bearings on the frame. This crank-shaft carries a tight pulley F and a loose pulley G on one end and a fly-wheel f on its other end. Motion is imparted to the crank-shaft by means of a belt operating on the tight pulley F, this belt being connected with a suitable source of power, and the belt is shifted from the tight to the loose pulley automatically to control the operation of the pump, and thereby regulate the supply of liquid to the mixer. A pipe g connects the pump with the top of the saturating-chamber, an air-chamber g' being located at a Vconvenient place in this pipe. This pipe g is provided with an upward eX- tension H, and a pipe 7L is connected to said extension and to a cylinder h', located adjacent to the pump. A piston I on a piston-rod operates in this cylinder 7i', and said piston-rod is connected to one arm of a bellcrank lever J, pivoted on the frame c, the other arm of said bell-crank being connected to a belt-shipper j. This bell-crank is normally held by the weight j so that the beltshipper will hold the belt on the tight pulley F; but when the piston in the cylinder is forced upward, as hereinafter described, the

bell-crank will be operated and the belt shipped to the loose pulley.

A double-seating wing-valve K is arranged to operate in the extension II, and when it is pushed upward the conical end 7c is raised from its seat to allow the passage of liquid from the pipe extension II to the pipe 71 and the conical end 7c is forced to its seat to prevent the liquid from passing up and out through the exhaust-pipe L, and when the valve is allowed to descend the conical end 7c' is lowered from its seat to permit the liquid in the pipe extension H to flow up and exhaust through the pipe L, while the conical end 7c is seated to prevent the further passage of liquid into the pipe Zt from the pipe extension H. This valve may be operated by different means, and in Fig. l I have shown a balanced tank for this purpose. This tank M is connected by a pipe m with the lower end of the tank A, and it is hung on one end of a lever m', pivoted on the tank A, the other end of said lever being provided with a weight Z. The weighted end of the lever passes through a yoke Z/ on the stem N of the valve K, and said stem is maintained normally in a vertical position by a guide n onthe collecting-tank. With this embodiment of my invention it will be observed that as the liquid rises in the collecting-tank Ait will also rise to a corresponding level in the balanced tank M, and when the proper level has been reached, which is regulated by the weight Z, the balanced tank will overcome said weight and rock the lever m', thereby raising the vvalve K and its conical end Zt from its seat and seating its conical end k. This change of position of the valve will allow the liquid forced by the pump through the pipe g to pass up through the extension II and into the pipe Zt and cylinder h, forcing the piston therein upward and moving the bell-crank lever J to lship the belt from the tight pulley F to the loose pulley G. The parts will be maintained in this position until the liquid in the collecting-tank A and the balanced tank M has lowered sufficiently to permit the weight Z to raise the balanced tank into its normal position, whereupon the valve K will be lowered and its conical end Zt seated to prevent the further passage of liquid upward through the extension H to the pipe h and unseating the conical end Zt to permit the liquid forced out of the cylinder h and the pipe ZL by the descent of the piston in said cylinder, under the induence of the weighty, to escape into the exhaust-pipe L. When the piston in the cylinder h descends, the bell-crank lever is of course moved to ship the belt from the loose to the tight pulley, which will set the pump in operation again. This operation is automatically repeated as the level of the liquid in the collecting-tank changes.

The valve K can be operated electrically to accomplish the same result in the manner shown in Fig. 4;. In this construction a oat O is arranged within the collecting-tank on an arm o, pivotally supported on a transverse shaft o', said arm being provided with lateral extensions P P, which are arranged to e11 gage spring-controlled contact devices p p. The valve-stem is connected to the springcontrolled armature-lever Q of the magnet q, and when the circuit connected with this magnet is closed, as shown, by the rise of the iioat O the armature on said lever will be attracted to its magnet and the trip-lever R engaged with said armature-lever to hold the same in this position. When the ioat in the tank is lowered to its normal position, the circuit just described is broken, and the armature carried by the trip-lever is attracted by its magnet, the armature-lever being thereby disengaged from the trip-lever to permit the valve K to resume its normal position. Various other forms of electrical devices may be employed for this purpose without departing from the spirit of my invention.

In order that the liquid may be discharged in the saturating-chamber in the form of a spray and in order also to regulate the discharge of liquid, I provide a regulating device, which consists of a spring-pressed cylinder S, having angularly-shaped openings s therein, arranged to register with squareshaped openings s' in an inclosing cylinder T, located at the end of the pipe g in the upper end of the saturating-chamber. The liquid flowing through the pipe g will pass through the openings s s', any number of which may be provided, and be distributed into the saturating-chamber, and it will be observed that as the pressure of the liquid increases or diminishes the cylinder S will adjust itself to bring a greater or less area of the openings s into register with the openings s', thereby relieving the pressure in the pipe g. Many different means may be employed for promoting the saturation of the liquid with the gas, and one very desirable method of accomplishing this end consists in allowing the liquid to pass through wire-gauze or similar material U, arranged Within the saturatingchamber in the form of a roll or otherwise. The liquid willpass through this gauze in the form of a very thin film, thereby allowing the gas to attack the same in the most favorable condition for a complete saturation.
